Tooth brushing is essential for the maintenance of oral health and in particular the prevention of Caries. The brushing process is a complex tribological contact which is influenced by a number of interrelated variables combining to cause the abrasion which results in the cleaning of the tooth surface. This process sits at a precipice where abrasion is required for cleaning but also has the potential to abrade and irreversibly damage the enamel surface. The ultimate goal in tooth paste development is a paste capable of high levels of stain removal with no enamel abrasion. Recent work has indicated that micronized spherical silica has the potential to reduce enamel and dentine abrasion while providing an enhanced level of cleaning, compared to standard angular silica.

刷牙对于维持口腔健康，尤其是预防龋齿至关重要。刷牙过程是一个复杂的摩擦学接触，受许多相互关联的变量的影响，这些变量结合起来引起磨损，从而导致牙齿表面清洁。这个过程位于清洁需要磨损的悬崖上，但也有可能磨损和不可逆地损坏牙釉质表面。牙膏发育中的最终目标是能够高水平去除污渍而没有搪瓷磨损的糊状物。最近的工作表明，与标准的角二氧化硅相比，微型化球形二氧化硅具有减少牙釉质和牙本质磨损的潜力，同时提供了增强的清洁水平。
